Insects of Britain and Ireland: the genera of Lepidoptera-Geometridae
Adults. Antennae of males simple; simply-ciliate. Face rough (with a slight cone of scales).
The outer margin of the forewing convexly curved. Forewings white, with brown markings and a grey terminal band; predominantly white; with a clear discal mark (this blackish); with a distinct median band (the band brown and contrasty, sometimes broken towards the hind nargin). Hindwings conspicuously patterned; white, with grey terminal banding; with a clear discal mark (this dark grey); transversely lined (a whitish subterminal line in the marginal grey band).
Vein 10 of the forewings arising independently of 9; arising out of 11 and anastomosing with 9 to form a simple areole. Hindwings exhibiting a tubular vein 5. Vein 5 of the hindwings arising from about the middle of the transverse vein, or arising from below the middle of the transverse vein (?). Vein 8 of the hindwings approximated to or anastomosed with the upper margin of the cell to the middle or beyond. Hindwing veins 6 and 7 stalked.
Posterior tibiae of males 4-spurred.
